l 4 Claims. (Cl. 98-40) This invention relates to refrigeration and more particularly to a refrigerating system having an improved means for distributing the conditioned air.

One object of this invention is to provide a system in which the conditioned air may be discharged vertically from the cabinet'or may be discharged horizontally from the cabinet.

Another object of this invention is to provide an improved grille for directing the flow of air.

Still another object, of this invention is to provide a refrigerating cabinet with a discharge opening adjacent on corner of the cabih'etand having improved means for directing the flow of air from the discharge opening.

Further objects and advantages of the present invention will be apparent from the following description, reference being had to the accompanying drawing, wherein a preferred form of the present invention is clearly shown.

In the drawing:

Fig. 1- is a sectional view showing a refrigerating system embodying features of my invention;

Fig. 2 is a fragmentary perspective view showing the outside of the air grille;

Fig. 3 is a fragmentary sectional view on an enlarged scale showing the details of the air deflector mechanism;

Fig, 4 is a. fragmentary sectional view taken on line 4-4 of Fig. 3; and

Fig; 5 is a fragmentary sectional view similar be observed that I have shown a main cabinet II) in which there is mounted a refrigerant liquefying system comprising a motor [2, a compresair deflectors 28 arranged behind the grille 26. In order to direct all of the conditi onedlair through the air defiectors '28,I"liave provided a -baflle"3ll"'which is provided with openings 33 to Fig. 3 but on a reduced scale and showing the air deflector rotated 180 from the position in which it is shown in Figs. 1 and 3.

In arranging an air conditioning unit within the room it frequently happens that it is necessary to place the conditioning unit in a certain comer or adjacent a certain wall in the room even though the location'is not the best suited from the standpoint of properly distributing conditioned air. It also frequently happens that these units are transferred from one location to another location, and this being the case it is necessary to provide simple means for directing the flow of air from the conditioning cabinet. In some installations it is desirable to in other installations the most desirable arrangement is to discharge the air horizontally or at some intermediate angle. 1 have designed V a refrigerating system which makes it possible to use a sameair grille construction for all types of installations.

' discharge the air substantially vertically, while Referring now to Fig. 1 of the drawing, it will slightly larger than the outside dimensions of the air deflectors 28. Each deflector 28 is rotatably supported by means of the shaft 32 which is rotatably supported on the grille 26 at 34. A knob 36 is provided on the outer end of each shaft 32 whereby the deflectors may-be manually adjusted from time to time. By virtue of the fact that the air deflector 28 is mounted at a 45 angle with respect to the vertical wall of the cabinet and by virtue of the fact that the airg'rille 26 has a vertical portion 21 and a horizontal portion 29, it is possible to discharge the air from the grille in a vertical direction through the portion 29 or in a horizontal direction through the portion 21. In the old arrangements where the air discharge opening is arranged in a single plane, it is impossible to direct the flow of air from thecabinet in either a vertical direction or a horizontal direction.

The baffle 30 is secured to the grille 26 by any suitable means such as welding. The grille 26 in turn is secured to the cabinet by means of screws 40. A resilient gasket, preferably of good heat of. the grille 26 and the inner surfacepf the cabinet Ill. The cabinet I0 is provided with 'an integral flange portion 44 which conceals the gasket 42 but does not come in direct contact with the grille 26. By virtue of this arrangement, the grille is recessed whereby the surface of thegrille is not exposed to any appreciable extent to the relatively warm room air which is caused to rush in over the outer surface of the cabinet adjacent the air discharge opening when the cold air is being discharged from the discharge opening. In the old type of installation where the air grille has a flange which is mounted flush with the outer surface of the cabinet or is slightly raised above the outer surface of the cabinet, a considgrille cools the air grille below the dew point of and 52 adjacent the bottom of the cabinet. The

condenser compartment adjacent the top of the condenser compartment. For purposes of illustration the condenser has been shown as being an air cooled condenser. However, it is obvious that any type of condenser may be used. It is likewise obvious that special air'ducts may be used for bringing condenser air into the room from the outside and for discharging the heated condenser air to the outside.

While the form of embodiment of the invention as herein disclosed, constitutes a preferred form, it is to be understood that other forms might be adopted, all coming within the scope of the claims which follow.

What is claimed is as follows:

1. In combination, a cabinet having a vertical wall and an intersecting horizontal wall, a disheated air leaves the through the opening 54 charge opening at the intersection of said walls,-

an air grille for said opening having a horizontal portion and a vertical portion, air conditioning means within said cabinet, air circulating means for drawing air into said cabinet, passing it through the air conditioning means and discharging it through said opening, and a rotatably mounted air directing means having a plurality of vanes arranged behind said grille for deflecting the air discharged through said opening.

2. In combination, a cabinet, means within said cabinet for cooling air, means for circulating a stream of air in thermal exchange relationsaid air cooling means, an air outlet in said cabinet for said stream of air, said outlet having a vertical component and a horizontal component, air deflecting means adjacent said ship with outlet, and means for adjusting said air, deflect ing means so as to discharge the air either horizontally or vertically.

3. In combination, a cabinet having vertical side walls and an intersecting top wall, means within said cabinet for cooling air, means for circulating a stream of air in thermal-exchange relationship with said air cooling means, air outlet means for said stream of air at the intersection of two of said walls, said air outlet means having one component in the plane of one of said walls and another component in the plane of another of said walls, air deflecting means adjacent said air outlet means, and means for adjusting said air deflecting means so as to discharge the air substantially perpendicularly to either one of said components.

i. In combination, a cabinet having vertical side walls and an intersecting top wall, means within said cabinet for conditioning air, means for circulating a stream of air in thermal exchange relationship with said air conditioning means, airoutlet means for said stream of air at the intersection of two of said walls, said air outlet means having one component in the plane of one of said walls and another component in the plane of another of said walls, air deflecting means adjacent said air outlet means, and means for adjusting said air deflecting means so as to discharge the air substantially perpendicularly to either one of said components.
